Answer:

The kinetic energy is 0J

Explanation: Mechanical energy is as much of potential and kinetic energy. Mechanical energy is never lost but only transformed from one form to another. As long as all the mechanical energy is as much as the potential energy then the kinetic energy is 0J. The mechanical energy of an object is found by summing its potential energy and kinetic energy.

Answer:

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

Answer:

Hello! The main thing I will be talking about today is two things that negatively affect the Earth's environment. Humans have impacted the physical environment is many ways, two being, overpopulation. Overpopulation is becoming a problem in this world. Accidental births are the main reason. Overpopulation can cause economic problems, over-farming, deforestation, and even water polluting. Second thing is, burning toxic fumes, and creating pollution. Pollution is a very, very bad thing. It can cause the atmosphere to fill up with fumes which aren't good for plants, humans, or animals. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. There are four main types of air pollution sources: mobile sources,  such as cars, buses, planes, trucks, and trains. stationary sources, such as power plants, oil refineries, industrial facilities, and factories. area sources, such as agricultural areas, cities, and wood burning fireplaces. I know the things I'm discussing are bad because, slowly the Earth is taking impact because of us. We need to make a better change and help our Earth.

An example of chemical weathering are;

Chemical Weathering can be described as the type of weathering that do take place due to the breaking down of the rock particles into smaller pieces which is usually as a result of chemical process.

It should be noted that when the process is taking place it scould be due to the  Extreme heat and pressure  which can affect the composition of the particles and as  a result of this there could be formation of products from the break down.

Explanation:

The increase in sunlight up to a limit might result in an increase in the photosynthesis process as well as in transpiration. More amount of energy will be produced by plants.

Answer: D) longer wavelength.

Explanation:

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s

kinetic energy is given as

2) when speed is 3 m/s

kinetic energy is given as

3) when speed is 4 m/s

kinetic energy is given as

4) when speed is 5 m/s

kinetic energy is given as

5) when speed is 6 m/s

kinetic energy is given as

+6.

Explanation:

So, a chromium atom here has an oxidation number of +6.

Rocks expand and contract when they are heated and cooled which cause them to break. Physical weathering is experienced to the crust of earth. The last state of physical weathering is sand. Rocks that have some cracks are undergoing frost wedging.

Weathering is a geographical process of deterioration of rocks and minerals into parts and eventually into dust and sand. Thermal stress, a phenomenon caused by temperature variations, can also contribute to mechanical weathering.

The expansion and contraction of rock is influenced by temperature changes. The rock's structure deteriorates as this occurs repeatedly. Physical weathering and mechanical weathering disintegrates rocks without any chemical changes and  it happens to the earth's crust.

Erosion of rocks eventually results in formation of sand. Frost wedging is a process by which ice erodes the rocks having cracks. It is also called ice wedging.

Answer: Hello: ) ✨ It depends on the concentration of all solutes in the solution (ie, its osmolarity). A solution with low osmolarity is hypotonic and vice versa. Solutions having the same osmolarity are isotonic. Water in pools and rivers is hypotonic compared with sea water, but water from the Dead Sea is hypertonic.We do not swell and pop when we go swimming in a hypotonic swimming pool because our skin protects us from the external environment and does not let water cross into or out of our body surfaces. ... hope this helps have a great dayAssuming the water is warm enough that you don’t simply die of hypothermia, the next problem would be your skin. For reasons that still aren’t well understood, human skin starts to break down after continuous immersion in water of a few days. You’d suffer open sores and be liable to fungal and bacterial infections just from the spores on your skin, even if the water itself was perfectly sterile. The pressure of the water also reduces the circulation to your extremities and makes breathing more difficult.

Explanation:

A relative term, hypotonicity defines a solution's characteristic in relation to another solution.

The cytosolic fluid or the fluid found inside a cell is frequently used as the comparison solution in biology. Therefore, a solution would be considered hypotonic in biology if it contained fewer solutes than the cytosol of a cell. The semipermeable membrane is the cell membrane. What then occurs to a cell in a hypotonic environment.

Tonicity has the prefix "hyper," which denotes "more" or "excess." Consequently, a solution that contains more non-penetrating solutes than the other solution can pass through a semipermeable barrier.

Therefore, A relative term, hypotonicity defines a solution's characteristic in relation to another solution.

Answer:

Explanation:In particular, eukaryotic cells divide using the processes of mitosis and meiosis. Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell.

A parent cell is the cell that divides during cell division to produce two daughter cells. The two daughter cells produced during mitosis share the same genetic makeup as the parent cell. In meiosis, the daughter cells have half as many chromosomes as the parent cell and a distinct genetic makeup.

A parent cell that is a progenitor of other cells or the first in a line of growing cells, as well as a cell that divides to produce two or more daughter cells.

The cell that divides into two daughter cells during cell division is referred to as the mother or parent cell. The mother cell's genetic makeup is carried over into the two daughter cells created during mitosis.

An organism's reproductive cells are called gametes. They are additionally known as sex cells. Male gametes are referred to as sperm, whereas female gametes are referred to as ova or egg cells. Each haploid cell that makes up a gamete has one copy of each chromosome.

The water from the ground rises to the sky and makes clouds. When the clouds become dark then rain or snow fall to the ground.

Water droplets make up clouds. These water droplets fall to Earth as rain when they get too heavy to remain suspended in the cloud.

Droplets of water make up clouds. Water droplets become larger when they condense onto one another within a cloud. Raindrops descend to Earth when these water droplets become too heavy to remain suspended in the cloud.

The water cycle on Earth, which is essential to all life, includes both rain and snow as important components.
